查询词典 peat bog

The study has shown:(1) With increasing sediment depth and the woody giblets, the total organic carbon, the extraction of benzene , the total humic acids and the unhydrolyte are enhanced, while the hydrolyte is decreasing.(2) According to the GC-MS analysis, n-alkane,n-alkan-2-ones and n-alkanones are composed mainly of long-chains,such a result is thought to be characteristic of a herbaceous input from 2300a.B.P. n-alkanones exist in the samples may be considered as the evidence of microorganisms activity.(3) It is showed that the lipids is more sensitive to the climate change than the floristic. The proxy of the pollen spore of the peat stratum is different from the normal environment proxy. It is one of the main reasons that the sensitivity difference of the bog vegetation reacting to the climate isn't accordant with the log of the fat molecule fossil and biology fossil.(4) The transformation of the peat organic carbon is under the influence of temperature,acidity,organic material constituting, etc, and it showed the up-trend with the depth. In the short-term scale, the conversion of the peat organic carbon is effected by seasonal water,regional climate and vegetations; while in the long-term scale, it is controlled mainly by the climate.(5) According to the comparing the orderliness of organic compound,vegetation giblets with the depth to the characteristics of the peat molecule fossil with the section, in the development of this peatmire, 1500a B.P（210cm）is regard as the borderline of the late Holocene, the keynote of the front period is warm with several cold fluctuations, and the trend of the back period is dry and cold although there were several fluctuations.

研究表明：（1）随深度的增高及植物残体中木本残体的增多，总有机碳、苯萃取物、总腐植酸、不被水解物含量逐渐增高，而易水解物含量减少；（2）GC- MS分析显示，正构烷烃，直链烷基2-酮和正烷醇均以长链组分为主，揭示了该泥炭柱剖面2347a.B.P的母源输入以草本植物为主；甲基酮类和短链正烷醇的存在是微生物活性很大的生物证据；（3）通过有机分子标志物与孢粉、植物残体等指标的对比研究表明：脂类化合物对气候变化的反映要比植物种灵敏得多，不同沼泽植物对气候变化的敏感性的差异是脂类分子化石记录与生物大化石结果很难一致的主要原因之一；（4）泥炭有机碳的转化受到温度、酸度、有机物质组成等很多因素的影响，短时间尺度，泥炭有机碳的转化受季节性降水、地方气候和植被等因素的影响；长时间尺度，泥炭地有机碳的转化，受气候条件控制；（5）总结泥炭分子化石特征、泥炭有机质各组分含量及植物残体组成随深度的变异规律，分析结果显示该泥炭地层形成过程中，1500a B.P（210cm）可作为划分前后晚全新世的界线，前期的基调是气候偏暖，但又有几次偏干冷气候的反复，后期气候以干冷为主，其间虽有几次上升波动，但整体趋势不变。

Wetland refers to natural or artificial, permanent or temporary marshes, peat bog and waters(motionless or flowing, fresh water or salt water) including sea area no deep than 6m in low tide.

湿地是指天然或人工的、永久或暂时性的沼泽地、泥炭地和水域（有静止或流动、淡水或咸水水体），包括低潮时水深浅于6米的海水区。

Bogwood: Wood that has been preservedin a peat bog.

泥炭木：沼木久埋于泥炭沼泽之中的树木。

They went to work at once, plowing, barrowing,rolling, furrowing, in admirable order, as if they were bent on making this a model farm; but when I was looking sharp to see what kind of seed they dropped into the furrow, a gang of fellows by my side suddenly began to hook up the virgin mould itself, with a peculiar jerk, clean down to the sand, or rather the water —— for it was a very springy soil —— indeed all the terra firma there was ——and haul it away on sleds, and then I guessed that they must be cutting peat in a bog.

他们立刻工作了，耕着，耙着，滚着，犁着，秩序井然，好像他们要把这里变成一个模范的农场：可是正在我睁大了眼睛看他们要播下什么种子的时候，我旁边的一群人突然开始钩起那处女地来了，猛的一动，就一直钩到沙地上，或者钩到水里，因为这是一片很松软的土地，——那儿的一切的大地都是这样，——立刻用一辆雪车把它载走了，那时候我猜想，他们一定是在泥沼里挖泥炭吧。

Wetland refers to natural or artificial, permanent or temporary marshes, peat bog and waters (motionless or flowing, fresh water or salt water) including coastal seawater areas no deep than 6m in low tide.

湿地指天然或人工，长久或暂时性的沼泽地，泥炭地或水域地带和水域（一动不动或流动，淡水或海水）包括沿海海水地区没有超过6米深低潮。

There are two types of coal formation: a local land accumulation in which the original substance of rotten plant material congregates in a peat bog where plants are growing; b distant land accumulation in which the original substance, which is from nearby areas or somewhere distant, of rotten plant coal congregates in a fresh water basin, lagoon, delta or lake through movements.

成煤原始物质的堆积方式分为2大类型：原地堆积——腐植煤的原始物质聚集在泥炭沼泽中植物自身繁殖的地方；异地堆积——腐植煤的原始物质是从相邻地区或大陆更远的一些地段，经过搬运，聚集在淡水盆地、泻湖、三角洲、湖泊之中。
